View Full Version : 509 just BOSCH on screen when turn on
Hi all!
509 just BOSCH on screen when turn on.
And it does not connect with softwares,
expect of reading IMEI in KOCI 2.30
Please help to resolve this problem.
Thanks!
use bosch eeprom r/w to fix the phone...simply copy a new binary file using that software coming from another phone and flash it to the phone you are repairing using again that software nadd after that PERMANENTLY BLOCKED will appear on the screen...Don't panic,just simplty unlock the phone using bosch unlocker by NEO to remove the permanently block of the phone....
this solution is 100% tested by me....
best regards and happy unlocking........
Great thanks for your message.
I lnow about this solution, but this phone does not contact with software, expect reading IMEI. And I cann't to write EEPROM :( And there are no phisical EEPROM :(
ADP 3402
if it still does not contact with any software try replacing " ADP 3402 " I.C. maybe that should help you solve your problem.
i tried it many times and tested 100%!!!

best regards and happy unlocking...

ADP located near CPU. Quite big chip. But I think this not solve your problem.
There are so much problems on Bosch 909 with damaged emulated EEPROM area.
I don't know good solution that helps in any case :(

The ADP3402 is a multifunction power management system IC
optimized for GSM cell phones. The wide input voltage range of
3.0 V to 7.0 V makes the ADP3402 ideal for both single cell
Li-Ion and three cell NiMH designs. The current consumption of
the ADP3402 has been optimized for maximum battery life,
featuring a ground current of only 230 mA when...

Hi friends!
I found a solution to fix freezing problem of some older Bosh
phones (509,607,Siemens S6..). If only "BOSH"appears on the display after power on and the LED on the top lights in red - 99%
it's not software problem! The phone doesn't pass battery check
test and freezes. So you must check the battery itself (2 rezistors inside) and in most cases connector of the battery.
Good luck
